Learn Xi argon welding
I. Introduction. Argon welding is a commonly used metal welding method that is widely used in industrial production.
By using the inert gas argon during the welding process, argon welding can effectively prevent the intrusion of oxygen and water vapor into the welding area, thereby reducing the generation of porosity and defects.
This article will introduce the basic principles, equipment and operation skills of argon electric joint welding, as well as some precautions for its practical application.
Second, the basic principle of argon welding.
Argon welding is a type of arc welding method in which the basic principle is to melt and join metal materials together by the heat of the arc.
During the welding process, the inert gas argon is used to protect the welding area from the ingress of oxygen and water vapor.
Argon has stable chemical properties and high thermal conductivity, which can effectively protect the welding area and provide enough heat to melt the metal material.
3. Argon electric welding equipment.
The equipment of argon and electric joint welding mainly includes welding machines, gas cylinders and gas delivery systems.
A welding machine is an argon electric joint welding equipment, which creates an arc by controlling the current and voltage and provides enough heat to melt the metal material.
A gas cylinder is a container where argon gas is stored, and a gas delivery system is used to transport argon gas to the welding area.
Fourth, the operation skills of argon electric welding.
The operation tips of argon joint welding include selecting the appropriate welding current and voltage, controlling the welding speed and welding angle, and maintaining the appropriate arc length.
Choosing the right welding current and voltage is the key to welding quality, too high or too low current and voltage will affect the quality of the weld.
Controlling the welding speed and welding angle can make the weld uniform and free of obvious defects.
Maintaining the proper arc length provides enough heat to melt the metal and avoids porosity and defects.
5. Precautions for argon electric welding.
When carrying out argon electric welding, the following points need to be noted.
First of all, the welding area should be clean and free of grease and impurities.
Secondly, the selection of welding materials should match the welding method and welding materials to ensure the welding quality.
Finally, operators need to wear appropriate personal protective equipment, including welding masks, gloves, and coveralls, to protect against arc damage.
VI. Conclusions. Argon welding is a commonly used metal welding method that can effectively prevent the intrusion of oxygen and water vapor by using the inert gas argon to protect the welding area, thereby reducing the generation of porosity and defects.
When performing argon welding, it is necessary to pay attention to selecting the appropriate welding current and voltage, controlling the welding speed and welding angle, and maintaining the appropriate arc length.
